The information in this document suggests that Oscillating Wind Energy Conversion Systems do not appear to have any significant advantages over equivalent conventional rotating-element wind energy conversion systems. In fact, in most cases it appears that they have several disadvantages. The document addresses the oscillating cable-type wind energy conversion system as well as the oscillating vane and the oscillating wing. The advantages and disadvantages of each type of system are evaluated, and in each case a comparison is made between it and a conventional rotating-element wind energy conversion device. It appears unlikely that any of the oscillating element concepts can compete with the present generation of conventional wind energy systems.
